Struct Span

pub struct Span {
    pub start: usize,
    pub end: usize,
}

Represents a span of characters in the source code.

A Span contains the starting and ending indices of a span of characters in the source code. The start field represents the index of the first character in the span, while the end field represents the index of the last character in the span.

Fields

start: usize

end: usize

Implementations

impl Span

pub fn new(start: usize, end: usize) -> Span

Creates a new Span with the specified start and end positions.

Arguments

• start - The starting position of the span.
• end - The ending position of the span.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Span

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Span

fn eq(&self, other: &Span) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Span

Implements the Serialize trait for the Span struct.

This allows the Span struct to be serialized into a JSON object.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
